Reply to comment by MattC1977 in NASA’s DART data validates kinetic impact as planetary defense method | DART altered the orbit of the asteroid moonlet Dimorphos by 33 minutes by mepper

It translates to minutes. Dimorphos completes an orbit in 33 fewer minutes than it did before it got smacked.

So it's orbital speed and orbit changed by how much? In relation to it's parent body?

Well if its orbit takes 1 year to complete then it equates to changing the orbital speed/period around the sun by 0.0057%

In this case Dimorphos orbits another asteriod, and has an orbital period of a few hours.
